Because the initial quantity given is \(K_b\) rather than \(pK_b\), we can use Equation \(\ref{16.5.10}\): \(K_aK_b = K_w\). Consider, for example, the ionization of hydrocyanic acid (\(HCN\)) in water to produce an acidic solution, and the reaction of \(CN^\) with water to produce a basic solution: \[HCN_{(aq)} \rightleftharpoons H^+_{(aq)}+CN^_{(aq)} \label{16.5.6} \], \[CN^_{(aq)}+H_2O_{(l)} \rightleftharpoons OH^_{(aq)}+HCN_{(aq)} \label{16.5.7} \]. Hence the \(pK_b\) of \(SO_4^{2}\) is 14.00 1.99 = 12.01. Acid HA A-Ka pKa Acid Strength Conjugate Base Strength Hydroiodic HI I-Hydrobromic HBr Br-Perchloric HClO4 ClO4-Hydrochloric HCl Cl-Chloric HClO3 ClO3-Sulfuric (1) H2SO4 HSO4-Nitric HNO3 NO3-Strong acids completely dissociate in aq solution (Ka > 1, pKa < 1). The values of \(K_b\) for a number of common weak bases are given in Table \(\PageIndex{2}\). Nitric acid is highly corrosive. Your Safer Source for Science. The Ka value of ammonium (NH4+) is 5.6*10-10, the Kb value of ammonia (NH3) 1.8*10-5, is ammonium more strongly acidic than ammonia is basic? One method is to use a solvent such as anhydrous acetic acid. Nitric acid (HNO) is a colorless liquid with yellow or red fumes with an acrid odor. Base. Charles Ophardt, Professor Emeritus, Elmhurst College. are hidden by default. This would be a simple mass particle and let me go get my mona math of nitric, acid, nitric acid, which will be 484959 plus 63. Thus the conjugate base of a strong acid is a very weak base, and the conjugate base of a very weak acid is a strong base. Thus sulfate is a rather weak base, whereas \(OH^\) is a strong base, so the equilibrium shown in Equation \(\ref{16.6}\) lies to the left. The Brnsted-Lowry theory describes acid-base interactions in terms of proton transfer between chemical species. Hydrochloric Acid. The higher the Ka, the stronger the acid is, and the weaker its conjugate base is. The equilibrium will therefore lie to the right, favoring the formation of the weaker acidbase pair: \[ \underset{\text{stronger acid}}{CH_3CH_2CO_2H_{(aq)}} + \underset{\text{stronger base}}{CN^-_{(aq)}} \ce{<=>>} \underset{\text{weaker base}}{CH_3CH_2CO^-_{2(aq)}} +\underset{\text{weaker acid}} {HCN_{(aq)}} \nonumber \], A Video Discussing Polyprotic Acids: Polyprotic Acids [youtu.be]. Calculate \(K_b\) and \(pK_b\) of the butyrate ion (\(CH_3CH_2CH_2CO_2^\)). "Acid-Base Equilibria." density of nitric acid is equal to 1 512.9 kg/m; at 20C (68F or 293.15K) at standard atmospheric pressure . u Assumes about one-third of acid is effective since phosphoric acid does not completely dissociate. The equilibrium constant expression for the ionization of HCN is as follows: \[K_a=\dfrac{[H^+][CN^]}{[HCN]} \label{16.5.8} \]. The fully protonated species is always the strongest acid because it is easier to remove a proton from a neutral molecule than from a negatively charged ion. Input a temperature and density within the range of the table to calculate for Hence the ionization equilibrium lies virtually all the way to the right, as represented by a single arrow: \[HCl_{(aq)} + H_2O_{(l)} \rightarrow H_3O^+_{(aq)}+Cl^_{(aq)} \label{16.5.17} \]. Because nitric acid is a strong acid, we assume the reaction goes to completion. An example of a weak acid is acetic acid (ethanoic acid), and an example of a weak base is ammonia. In contrast, acetic acid is a weak acid, and water is a weak base. The experiment has possibilities for use as an assessed practical. One specication for white fuming nitric acid is that it has a maximum of 2% . This leads to the statement that acids and bases are not all of equal strength in producing H+ and OH- ions in solution. The Complete Aqueous Hydrochloric Acid Solutions Density-Concentration Calculator. This article will provide you with the molarity definition and the molarity formula.. To understand the topic as a whole, you will want to learn the mole . When the acid concentration is . Most commercially available nitric acid has a concentration of 68% in water. Similarly, the equilibrium constant for the reaction of a weak base with water is the base ionization constant (\(K_b\)). In presence of strong acids like sulfuric acid, HNO 3 acts as the base because it has to accept the proton from the stronger acid. Acid & Base Molarity & Normality Calculator . When placed in water, virtually every HCl molecule splits into a H + ion and a Cl - ion in the reaction. H 3 O+. Note that some fields (mol, advanced pH calculations, etc.) So 1 US gallon = 3.78 litres, Then 130 x 3.78 = 491 litres of liquid volume. Formula: Density = weight / volume or Volume = weight / density or Volume of 100 gram of Nitric acid: 100/1.413 = 70.771 ml Note: 70% (w/w) Nitric acid means that 100 g of Nitric acid contain 70 g of HNO3. The weaker the bond, the lesser the energy required to break it. To do this, a small sample is titrated to find its acidity, which tells us how much base we need to neutralize the batch successfully. Although exact determination is impossible, titration is a valuable tool for finding the molarity. Because percent solutions can be expressed in three different ways, it is imperative that the type of percent solution be explicitly stated. A standard acid-base titration uses a titrant of known concentration to titrate a tank of unknown concentration. again. Thus the proton is bound to the stronger base. The conjugate acidbase pairs are \(NH_4^+/NH_3\) and \(HPO_4^{2}/PO_4^{3}\). Answer (1 of 3): If you have a solution of nitric acid of unknown concentration, there are a few ways to determine that. The light bulb circuit is incomplete. At the bottom left of Figure \(\PageIndex{2}\) are the common strong acids; at the top right are the most common strong bases. The constants \(K_a\) and \(K_b\) are related as shown in Equation \(\ref{16.5.10}\). Other factors may also be important when deciding on the type of percent solution to prepare. My second question is: let's a calculate number of grams of zinc to react to produce 29.1 grams of f h, 4. Our chemical concentration sensors can handle the most difficult acids, including hydrofluoric acid and oleum. Accessibility StatementFor more information contact us atinfo@libretexts.orgor check out our status page at https://status.libretexts.org. Enter appropriate values in all cells except the one you wish to calculate. Some chemists and analysts prefer to work in acid concentration units of Molarity (moles/liter). Add the indicator to the flask. Concentration Before Dilution (C1) %. If this information is not provided, the end user is left to "guess" whether w/v %, w/w %, or v/v % was used. Formula. Nitric acid is HNO3, and nitric acid reacts with water to form hydronium, H3O plus, and nitrate, NO3 minus, which is the conjugate base 2HNO3. If we add Equations \(\ref{16.5.6}\) and \(\ref{16.5.7}\), we obtain the following: In this case, the sum of the reactions described by \(K_a\) and \(K_b\) is the equation for the autoionization of water, and the product of the two equilibrium constants is \(K_w\): Thus if we know either \(K_a\) for an acid or \(K_b\) for its conjugate base, we can calculate the other equilibrium constant for any conjugate acidbase pair. University of Maiduguri. C6H5COOH\text{C}_6\text{H}_5\text{COOH}C6H5COOH. It is a highly corrosive mineral acid. The solution dilution calculator tool calculates the volume of stock concentrate to add to achieve a specified volume and concentration. Rationalize trends in acid-base strength in relation to molecular structure; . Legal. The curve around the equivalence point will be relatively steep and smooth when working with a strong acid and a strong . Name. From Table \(\PageIndex{1}\), we see that the \(pK_a\) of \(HSO_4^\) is 1.99. Acidbase reactions always proceed in the direction that produces the weaker acidbase pair. Find the pH of 0.5 grams of HCl disolved into 100 ml of water: 0.5 grams / (36.5 g/mole) = 0.014 moles HCl, HCl is a strong acid and completely dissociates in water, therefore the pH will be equal to the negative logarithm of the concentration of HCl. 4. For example, garlic seems to be a potent method for improving your body's . Water . The instructor will test the conductivity of various solutions with a light bulb apparatus. By adding either an acid or a base with a known molarity (the titrant) and measuring how much is needed to cause this change, we can work out the molarity of the unknown using the equation below: Here is the method for an acid-base titration: Fill a burette with the solution of the titrant. Point my first question. Like all equilibrium constants, acid-base ionization constants are actually measured in terms of the activities of H + or OH , thus making them unitless. 2. It was not until Mohr developed the modern burette in 1855 that the technique would become recognizable to us today and has since become a popular method of performing analytical chemistry. Thus, solution mass is the combined mass of solute and solvent, and solution volume is the combined volume of solute . (d) The acid H3PO3 has a pKa of 1.8, and this led to some insight into its structure. Nitric Acid is a strong acid in terms of chemical ionization and solutions of it can be assayed using a strong base, such as Sodium Hydroxide. They are also highly resistant to temperature changes. pH is calculated by taking the negative logarithm of the concentration of hydronium ions. Check out 19 similar mixtures and solutions calculators , Table of common acids and bases and their strengths. When the color change becomes slow, start adding the titrant dropwise. Strong acids have mostly ions in solution, therefore the bonds holding H and A together must be weak. It is then easy to see why French chemist Joesph Louis Gay-Lussac first used the term when performing early experiments into the atomic composition of materials (he would later go on to improve the burette and invent the pipette). Instead, a pH meter is often used. Factors Affecting Acid Strength. The bonds are represented as: where A is a negative ion, and M is a positive ion. for suppose, 100ml of 0.5% Nitric acid need to be prepared, and 'q' is the quantity (in ml) of 69% Nitric acid required, we calculate the 'q' from above equation. Similarly, in the reaction of ammonia with water, the hydroxide ion is a strong base, and ammonia is a weak base, whereas the ammonium ion is a stronger acid than water. By using a solution with a known molarity and a color indicator, we measure how much of the solution is required to neutralize the unknown solution, indicated by a change in the indicator, which we can use to work out information about the unknown solution. Thus nitric acid should properly be written as \(HONO_2\). If the circuit is completed by a solution containing a large number of ions, the light bulb will glow brightly indicating a strong ability to conduct electricity as shown for HCl. Our titration calculator will help you never have to ask "how do I calculate titrations?" Also your multiplication factor looks like the one for sulphuric acid. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. However, if you have two unknowns (the starting nitric acid concentration and the amount of sodium bicarbonate addition) you would need to first determine the concentration of the nitric acid with a standard acid-base titration. When placed in water, virtually every HCl molecule splits into a H+ ion and a Cl- ion in the reaction.1, \[\ce{HCl(aq) + H2O(l) <=> H3O^{+}(aq) + Cl^{-}(aq)} \nonumber\], For a strong acid like HCl, if you place 1 mole of HCl in a liter of water, you will get roughly 1 mole of H30+ ions and 1 mole of Cl- ions. For example, adding 50 mL of water to 50 mL of water will result in a total volume of 100 mL, and adding 75 mL of 100% ethanol to 75 mL of 100% ethanol will result in a total volume of 150 mL. Once again, the activity of water has a value of 1, so water does not appear in the equilibrium constant expression. The indicator will change colour when this 1:11:11:1 ratio (governed by its titration curve) is achieved. Calculate the molality of nitric acid solution a) 29.0 b) 11.0 c) 43.2 d) 16.0 Question 8 (10 points) A concentrated aqueous solution of nitric acid (HNO3) has a density . The word titration comes from the French word tiltre, originally meaning the "proportion of gold or silver in coins," later meaning the "concentration of a substance in a given sample." Asked for: corresponding \(K_b\) and \(pK_b\), \(K_a\) and \(pK_a\). The terms "strong" and "weak" give an indication of the strength of an acid or base. We can use the relative strengths of acids and bases to predict the direction of an acidbase reaction by following a single rule: an acidbase equilibrium always favors the side with the weaker acid and base, as indicated by these arrows: \[\text{stronger acid + stronger base} \ce{ <=>>} \text{weaker acid + weaker base} \nonumber \]. If the structure of the acid were P(OH)3, what would be its predicted pKa value? The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. TCC's nitric acid belongs to the group of inorganic acids. Weak acids do not readily break apart as ions but remain bonded together as molecules. concentration (% weight) of Nitric Acid (HNO3) solutions in water at different temperatures in degrees centigrade (C). For example, when using a strong acid and a weak base, an indicator that changes at a low pH is needed, such as methyl orange (3.1-4.4). The \(HSO_4^\) ion is also a very weak base (\(pK_a\) of \(H_2SO_4\) = 2.0, \(pK_b\) of \(HSO_4^ = 14 (2.0) = 16\)), which is consistent with what we expect for the conjugate base of a strong acid. Acid & Base Molarity & Normality Calculator. This calculator calculates for concentration or density values that are between those given in the table below by a process called interpolation. [3] White fuming nitric acid, also called 100% nitric acid or WFNA, is very close to anhydrous nitric acid. To convert mass to moles, we need the molecular weight. Predict whether the equilibrium for each reaction lies to the left or the right as written. Nitric acid is colorless when pure but has a yellowish appearance when it is old due to the collection of nitrogen oxides. National Center for Biotechnology Information. Phosphoric acid is sometimes used but is somewhat less common. All the other mixtures show a weight loss not exceeding 2% even after 56 days immersion. The hydrogen ion concentration decreases by a factor of 10, so the pH increases by 1 . A. Hi Ryan, For a 25% v/v nitric acid solution you will need 130/4 = 32.5 litres of acid. In contrast, in the second reaction, appreciable quantities of both \(HSO_4^\) and \(SO_4^{2}\) are present at equilibrium. Hence, the acid is strong. Acids and bases behave differently in solution based on their strength. If we are given any one of these four quantities for an acid or a base (\(K_a\), \(pK_a\), \(K_b\), or \(pK_b\)), we can calculate the other three. Click here for more Density-Concentration Calculators. To know the relationship between acid or base strength and the magnitude of \(K_a\), \(K_b\), \(pK_a\), and \(pK_b\). At 25C, \(pK_a + pK_b = 14.00\). About Nitric acid. These experiments are helpful in monitoring the amount of pollution in the upper atmosphere. The odd H3PO3 Use the relationships pK = log K and K = 10pK (Equations \(\ref{16.5.11}\) and \(\ref{16.5.13}\)) to convert between \(K_a\) and \(pK_a\) or \(K_b\) and \(pK_b\). Keep in mind, though, that free \(H^+\) does not exist in aqueous solutions and that a proton is transferred to \(H_2O\) in all acid ionization reactions to form hydronium ions, \(H_3O^+\). If the acid or base conducts electricity weakly, it is a weak acid or base. The leveling effect applies to solutions of strong bases as well: In aqueous solution, any base stronger than OH is leveled to the strength of OH because OH is the strongest base that can exist in equilibrium with water. Nitric acid is the inorganic compound with the formula H N O 3. Total volume of solution including acid/base (liters): Calculate . Relevant comments and/or instructions will appear here after a calculation is performed. Find the normality of 0.321 g sodium carbonate in a 250 mL solution. According to the reaction equation. Each percent solution is appropriate for a number of different applications. Equivalence point means the point during titration at which the titrant added has completely neutralized the analyte solution. (In fact, the \(pK_a\) of propionic acid is 4.87, compared to 4.76 for acetic acid, which makes propionic acid a slightly weaker acid than acetic acid.) S.G. 1.41. In a situation like this, the best approach is to look for a similar compound whose acidbase properties are listed. For example, commercial aqueous reagents, such as concentrated acids and bases, are typically expressed as weight/weight % solutions. { Acid_and_Base_Strength : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Calculating_A_Ka_Value_From_A_Measured_Ph : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Calculating_Equilibrium_Concentrations : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Fundamentals_of_Ionization_Constants : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Weak_Acids_and_Bases : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Weak_Acids_and_Bases_1 : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { Acid : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Acids_and_Bases_in_Aqueous_Solutions : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Acid_and_Base_Indicators : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Acid_Base_Reactions : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Acid_Base_Titrations : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Buffers : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Buffers_II : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Ionization_Constants : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Monoprotic_Versus_Polyprotic_Acids_And_Bases : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "acid strength", "base strength", "showtoc:no", "license:ccbyncsa", "licenseversion:40" ], https://chem.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fchem.libretexts.org%2FBookshelves%2FPhysical_and_Theoretical_Chemistry_Textbook_Maps%2FSupplemental_Modules_(Physical_and_Theoretical_Chemistry)%2FAcids_and_Bases%2FIonization_Constants%2FAcid_and_Base_Strength, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), Demonstration of Acid and Base Conductivity, status page at https://status.libretexts.org. Accessibility StatementFor more information contact us atinfo@libretexts.orgor check out our status page at https://status.libretexts.org. 5.4 * 10-2. Calculate \(K_a\) for lactic acid and \(pK_b\) and \(K_b\) for the lactate ion. Start adding the titrant slowly, swirling the Erlenmeyer flask constantly. The values of \(K_a\) for a number of common acids are given in Table \(\PageIndex{1}\). The larger the \(K_b\), the stronger the base and the higher the \(OH^\) concentration at equilibrium. The behavior for a 20% nitric acid concentration is almost the same, the difference being that NC shows a higher weight loss. The table was taken from "Perry's Chemical Engineers' Handbook" by Robert H. Perry, Don Green, Sixth Edition. Place the burette on a burette stand. 16.4: Acid Strength and the Acid Dissociation Constant (Ka) is shared under a CC BY-NC-SA 4.0 license and was authored, remixed, and/or curated by LibreTexts. The \(pK_a\) and \(pK_b\) for an acid and its conjugate base are related as shown in Equations \(\ref{16.5.15}\) and \(\ref{16.5.16}\). pH is 3.00. Polyprotic acids (and bases) lose (and gain) protons in a stepwise manner, with the fully protonated species being the strongest acid and the fully deprotonated species the strongest base. For example, propionic acid and acetic acid are identical except for the groups attached to the carbon atom of the carboxylic acid (\(\ce{CH_2CH_3}\) versus \(\ce{CH_3}\)), so we might expect the two compounds to have similar acidbase properties. Strong acid examples are hydrochloric acid (HCl), perchloric . An older density scale is occasionally seen, with concentrated nitric acid specied as 42 Baum. All acidbase equilibria favor the side with the weaker acid and base. Calculate \(K_a\) and \(pK_a\) of the dimethylammonium ion (\((CH_3)_2NH_2^+\)). HSO 4-Hydrogen sulfate ion. Measurements of the conductivity of 0.1 M solutions of both HI and \(HNO_3\) in acetic acid show that HI is completely dissociated, but \(HNO_3\) is only partially dissociated and behaves like a weak acid in this solvent. HClO 4. When different volumes of an identical solution are added together, the final volume will always be exactly the sum of the individual portions added. Volume Before Dilution (V1) Concentration After Dilution (C2) %. 8.84 Lb/Gal. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Nitric Acid (HNO 3) is a clear, colorless to slightly yellow inorganic acid. Consequently, the proton-transfer equilibria for these strong acids lie far to the right, and adding any of the common strong acids to water results in an essentially stoichiometric reaction of the acid with water to form a solution of the \(H_3O^+\) ion and the conjugate base of the acid. \[HA_{(aq)} \rightleftharpoons H^+_{(aq)}+A^_{(aq)} \label{16.5.3} \]. Therefore, when preparing volume/volume percent solutions, it is always better to dissolve the solute in solvent and then add additional solvent to bring the total. A conjugate acid, within the Brnsted-Lowry acid-base theory, is a chemical compound formed when an acid donates a proton (H +) to a basein other words, it is a base with a hydrogen ion added to it, as in the reverse reaction it loses a hydrogen ion. Solution Dilution Calculator. Therefore the solution of benzoic acid will have a lower pH. A similar concept applies to bases, except the reaction is different. The values of Ka for a number of common acids are given in Table 16.4.1. The best way is to titrate the acid with a base that you know the concentration of. Dilutions to Make a 1 Molar Solution 1. In fact, all six of the common strong acids that we first encountered in Chapter 4 have \(pK_a\) values less than zero, which means that they have a greater tendency to lose a proton than does the \(H_3O^+\) ion. To work out an unknown concentration of 0.15 mL HCl: Use the 1:1 ratio formula because one mole of HCl reacts with one mole of NaOH HCl + NaOH NaCl + H2O. Therefore x = 9 10-3 equivalent, because it is a monobasic acid, the mass of the titration equation of the acid is . Thus acid strength decreases with the loss of subsequent protons, and, correspondingly, the \(pK_a\) increases. Thus propionic acid should be a significantly stronger acid than \(HCN\). For example, to find the % w/v of a solution the calculation is: (Mass of Solute (g) / Volume of Solution (ml)) x 100. 11.3 Calculate the assay as percent nitric acid as follows: nitric acid, % by weight 5 VN 3 6301 W (2) where: V = corrected NaOH solution required for titration of the sample, mL, N = normality of the NaOH solution corrected for tempera-ture at time of titration, and W = sample used, g. 12. According to Table \(\PageIndex{1}\), HCN is a weak acid (pKa = 9.21) and \(CN^\) is a moderately weak base (pKb = 4.79). Strong acids easily break apart into ions. Exposure to nitric acid can cause irritation to the eyes, skin, and mucous membrane; it can also cause delayed pulmonary edema, pneumonitis, bronchitis, and dental erosion. That means number of moles of sulfuric acid is half that of number of moles of sodium hydroxide used. As we noted earlier, because water is the solvent, it has an activity equal to 1, so the \([H_2O]\) term in Equation \(\ref{16.5.2}\) is actually the \(\textit{a}_{H_2O}\), which is equal to 1. It is a strong acid, completely ionized into hydronium (H 3 O +) and nitrate (NO 3) ions in aqueous solution, and a powerful oxidizing agent (one that acts as electron acceptor in oxidation-reduction reactions ).
